Method for mechanically scraping boards, apparatus for same, and products made therewith

摘要

Methods are described for mechanically scraping surfaces of boards, such as flooring boards, to impart random-looking scraped profiles therein. An apparatus for mechanically scraping boards to form the scraped board products also is described. A board, such as a flooring board, having a random-looking scraped appearance that includes overlapping multiple scrape patterns is described. Boards, such as flooring boards, having a simulated rustic or distressed appearance made with the methods and apparatus also are described.

1. A method for imparting a simulated rustic or distressed surface effect in a flooring board comprising:
advancing flooring boards on a table, wherein the table comprises a board supporting surface and a plurality of slot openings in the board supporting surface through which different cutter heads having different cutting profiles protrude to be contactable with lower surfaces of the boards advancing thereover; engaging opposite lateral sides of the boards with first and second laterally movable fences concurrent with the advancing of the boards on the table; laterally moving the fences relative to the cutter heads; engaging lower surfaces of the board with liftable bed plates defining the slot openings in the table as the boards are advanced on the table; controlling said laterally moving and said liftable bed plates with at least one programmable controller to control at least one of the depth of cut or lateral cut position on the lower surface of boards, wherein different and at least partial, overlapping patterns of scrapes are formed in the lower surface of the boards by the different cutter heads.
